An area of dead or dying tissue produced by lack of blood flow and oxygen to or from that area. For example, myocardial infarctions is the death of heart muscle.
An infarct may occur when an artery is blocked by an obstruction, slowing or depleting the blood flow to a certain area of the body.
When an individual is involved in an accident, such as a motorcycle crash, he or she may have damaged arteries due to the injuries they sustain. As a result, blood flow can become restricted.
